These files include data and estimation code for:

Boehmke, Frederick J., Tracy L. Osborn and Emily U. Schilling. 2015. "Pivotal Politics and 
Initiative Use in the American States."  Political Research Quarterly 68 (4): 665-677.

Compiled on May 03, 2018 by Frederick J. Boehmke (frederick-boehmke@uiowa.edu).


INCLUDED:  

3 Stata data sets: 
 
  bos2015prq.dta 			Data on 24-state initiative use and pivot intervals.
  bos2015prq-CA.dta 			Data on California initiative use and pivot intervals.
  state legislator scores may 2013.dta	Shor and McCarty's data on state legislator ideal points.

2 Stata do files:  
 
  bos2015prq.do 			Runs the models reported in the paper.  
  bos2015prq-robust.do 			Runs the robustness analysis summarized in the paper.  
  
1 README file: 
  
  bos2015prq-README.txt			Describes the included data and files.  

  
NOTES:

1. There are two primary data sets: bos2015prq.dta contains the data for all
	24 initiative states and the various pivot intervals used as well as the
	data for California initiative use and its pivot intervals. 
		
2. The models for all 24 initiative states and the models for just California are 
	estimated by bos2015prq.do. It also includes various alternate models
	referenced in the paper.

3. The robustness analysis reported on at the end of the section "Pivotal 
	Politics and Initiative Use" is run in the file bos2015prq-robust.do. 

4. The robustness analysis uses Shor and McCarty's data on state legislator	
	ideal points. We include the version available to us when we ran 
	these models. See the following for more information:
	
	Shor, Boris, and Nolan McCarty. 2011. "The Ideological Mapping of 
	American Legislatures." American Political Science Review 105 (3): 530�51.
	
5. The programs are written for Stata version 12 or above, though they may run in 
	previous versions.
	
6. You will need to install estout.ado to generate the tables in bos2015prq.do.

7. You will need to install grc1leg.ado to generate the combined figures in 
	bos2015prq-robust.do.


VARIABLES:

Here are descriptions for all the variables included in the various data sets. 
See the paper for additional details.
